Flanked by the animatronic robots created in his workshops, Steve Jacobsen, an engineering professor at the University of Utah in Salt Lake City, may be the world's most entrepreneurial roboticist-he's spun off four companies from his research and discoveries. Perhaps the most important product he makes is the Utah Artificial Arm (above Jacobsen's head), a high-tech prosthetic hand used by thousands of amputees around the world. From the book Robo sapiens: Evolution of a New Species, page 216-217.
